Hi, keep in mind that the high frequency of urination may be due to urinary tract infection, diabetes or prostate disease, just to mention a few. I suggest you visit a urologist or a nephrologist who will properly diagnose and treat you. It is better to go for medical consultation rather than take self diagnosis or symptoms lightly.
 

To strengthen your bladder muscle, you can try pelvic floor exercises, maintain a healthy weight, stay hydrated. Avoid bladder irritants like certain foods and drinks such as caffeine, alcohol, spicy foods, and artificial sweeteners, can irritate the bladder. 

Have you ever felt a moment of pain below but there are no other symptoms: discharge burning sensation while urinating? If yes then it might not be anything serious. This type of ache can result from being hit or even just having an odd feeling. It is common and usually goes away by itself. Keep yourself hydrated; do not engage in strenuous activities and the discomfort will disappear within no time.

You might have this problem if you are feeling pain when passing urine if you feel like you need to pass urine more often than usual, or when your urine looks cloudy. A bladder infection happens when bacteria enter the bladder. However, it is not usually serious. To cure it, your doctor might give you some antibiotics that can help kill the germs causing the infection. Ensure that you drink a lot of water to help wash away the bacteria. 

You may have a condition called varicocele when the veins in your testicles are enlarged like the varicose veins in your legs. This can cause a scrotum that is swollen or heavy to feel. The epididymis is a coiled tube located behind the testicle, and it can also become inflamed, leading to pain and swelling. Varicoceles and epididymitis don't usually lead to serious problems, but it's important to see a doctor to confirm the diagnosis. The doctor might recommend wearing supportive underwear, taking pain medication, applying ice packs, and sometimes surgery in severe cases.

Your nephew was watched for high bilirubin, which is good. It’s a puzzle with a positive UTI and maybe PUV. Symptoms include fever and UTIs. PUV can block urine flow. Surgery might be necessary but it’s not clear from the X-ray. If there is no fever or symptoms, don’t hurry now. Continue working with the doctors.
